Trakd have partnered with a fast-growing fintech infrastructure play, backed by one of the UK’s most successful privately held investment and technology groups, expanding into Europe

We’re building the infrastructure behind the next generation of investing. Our technology already powers some of the UK’s most ambitious fintechs, banks, financial advisers and wealth firms, with close to a million investors relying on our platform and we’re now expanding into Europe. We’re backed by one of the UK’s most successful privately held investment and technology groups, giving us long-term stability with the pace of a high-growth business. We’re B Corp certified and believe profit and purpose go hand in hand.

Engineering is organised into four tribes, each owning a distinct product domain, made up of small autonomous squads (Engineering Manager, Product Manager, 3-5 engineers). We operate a build-and-run model - teams own the full lifecycle from architecture through to incident management. Stack: AWS serverless (Lambda, SQS, EventBridge, API Gateway, S3, ECS/Fargate), TypeScript/Node.js, MongoDB, some C#. Terraform + Serverless Framework for infra, GitHub Actions for CI/CD.
